WINDOW-SHADE APPLIANCE.

SPEOIFIOATION forming part of Letters Patent No. 516,315, dated March13, 1894.

Application filed y 1 893- To aZ Z whom it may concern:

Be 11: known that I, LAFAYETTE M. RICE, of Leavenworth, Leavenworthcounty, Kansas,

have invented certain new and useful Improvements in Window-ShadeAppliances, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to that class of window shade appliances, wherebythe shade is carried by the upward and downward movementof the uppersash, and winds or unwinds a distance corresponding to the downward orupward movement of the said sash, and whereby the shade may be alsowound or unwound independently of the movement of said sash; and theobjects of the invention are to produce a device of this character whichis positive and reliable in operation, and which is simple, strong,durable and inexpensive of construction.

To the above purposes my invention consists of certain peculiar andnovel features of construction and arrangement as hereinafter describedand claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in

Figure 1, is an inner face view of a window, and showing applied theretoin operative position a shade which is arranged in accordance with myinvention. Fig. 2, is a vertical sectional view taken on the line 22 ofFig. 1. Fig. 3, is a detail perspective view of one end of the shaderoller, and showing the mechanism by which it is carried and oper ated.Fig. 4, is a detail perspective view of the clamp and a portion of thecord for winding or unwinding the shade. Fig. 5, isa vertical sectionalview of the same, and also a detail perspective view of the clam pingwedgeplate for securing the ends of the cords together beneath theclamp. Fig. 6, is a detail perspective view of one end of one of theroller supporting brackets. Fig. 7, is a detail perspective view of abracket for use when a spring roller curtain is used in connection withthe invention. Fig. 8 is a ver- Serial No. 475.558. (No model.)

tical sectional view to show the manner of clamping the shade rolleroperating cord.

In the drawings, 1 designates a window casing, 2 designates, the lowersash thereof and 3 designates the upper sash thereof; these sashes beingconnected through the inedium of ropes 2 and 3 with the counter weights(not shown) in the ordinary manner.

In order that the curtain may be carried by the upper sash,I providebrackets, having the horizontal and inwardly projecting portion 4thereof, the sides of which are arranged to be vertical preferably, andthe foot portion 5 which is arranged at right angles to the portion 4,and is adapted to be secured by screws or other suitable means to andnear the upper ends of the side rails of the upper sash. The horizontalportions 4 of these brackets are also provided with a series of notches6 in their lower margins or edges, and are further provided at theirouter ends and lower edges each with a retaining and guide ear 7, and attheir upper edges with the depending retaining and guide ear 8, the ears8 being located a suitable'distanceinward of the ears 7 for a purpose tobe presently explained. A pair of brackets consisting of the bodyportion 9 which is of similar size and form as the portions 4 of thebrackets first mentioned, are provided at their lower margins and rearor outer ends with the rightangle flanges 10, and are also formed withthe arms 11, which when the said brackets are operatively carriedby thefirst mentioned brackets as hereinafter referred to, diverge outwardlyand upwardly as shown in Fig. 1, and each of said brackets is also bentto form cars 12 at the outer ends, which extend forwardly and upwardlyand parallel with each other. These ears 12 are provided with openings13 for the reception of trunnions or spindles of roller 14, which isthus supported by and between said ears in a horithe rear or outer endof the brackets having the right angle flanges 10, are arrangedobliquely, as shown in dotted linesin-FigJ3, so

that they may lie vertically against the side of the portions 4 of thebrackets secured to the upper sash. The brackets carrying the roller arenow operated pivotally so that their lower and upper margins will engagebetween the ears 7 and 8 respectively, and the right angled flanges 10will engage one or the other of the notches 6 in the under side of theportions 4, according to the distance the curtain roller is desired tobe held from the inner side of the window. It will thus be seen, that asthe upper sash is raised or lowered the roller carrying the curtain 14'will be carried with it.

In order that the curtain may be wound or unwound upon the roller duringthe upward or downward movement of the sash a pair of parallel cars 15is formed below the car 12 of one of the roller carrying brackets, andjournaled loosely to revolve between said cars is a grooved roller 16,which is arranged vertically beneath the roller 17 formed or socuredupon the adjacent spindle or trunnion of the curtain roller. Securednear the upper and lower ends of one of the side rails of the windowframe, and arranged in vertical alignment with the rollers 16 and 17 arethe brackets 18, and journaled to revolve between the ears of saidbrackets are the grooved rollers 19. A cord is passed over the upperroller 19, and is then carried downward in rear of the rollers 16 and17, the cord is then carried around and up the front side of the roller16 and diagonally upward and to the rear of the roller 17, and is thencarried over said roller and vertically downward beneath and to the rearof the lower roller 19, and the end is brought upwardly to meet and issecured to the opposite end thereof which is pendent from the upperroller 19; thus forming an endless cord by which the curtain may bewound upon the roller. In order that the two ends of the cord 20 may beeasily and quickly secured together, I provide a clampplate, which isformed with the two cylindrical passages 21 and 22; the portion 21 beingpreferably rigidly secured upon one end of the cord. The opposite end ofthe cord is then passed through the cylindrical passage 22, and asegmental wedge-plate 23 provided with holes 242-24: punchedtherethrough to form a roughened face on the inner side, has its smallerend inserted in the passage 22. The cord is now pulled in the directionof the arrow, Fig. 4, and the wedge-shaped plate 23 is forced into thepassage 21, and the roughened under side thereof formed by punching theholes 24 therethrough bites upon the cord and secures it firmly inposition.

When it is desired to prevent any accidental movement toward winding orunwinding the curtain, a pawl 25 which is pivoted at 26 to the windowframe adjacent to the lower roller 19, is thrown downwardly, andfrictionally engages that portion of the cord 20 which passes to therear of the lower roller 19. In

order that the upper sash may be operated for ventilation or otherpurposes, an ordinary cord 27 is secured at 28 to the upper rail of saidsash, and passes over a guide pulley 29 which is pendent from the upperhor zontal portion of the window casing; this cord 27 being preferablyarranged to pass upon opposite sides of the curtain 14. If preferred,the cord 27 may be secured as described, and have its pendent ends inrear of the curtain, and provided with tassels, as shown in Fig. 2.

Secured to the roller carrying brackets, preferably at the junction arms9 and 11 thereof, are the standards 30, the upper ends of which arearched forwardly and inwardly at 31, and are then bent to form the hooks32 at their forward ends. A cross rod 33 1s adapted to be supportedhorizontally in said hooks 82, and is designed for use as a detachablerod by which lace curtains may be carried. A bracket 34 may besubstituted for one of the roller carrying brackets and is formed with arectangular recess or opening 35 for the reception of the squaredsplndle of a spring roller curtain when such 1s used.

When a spring roller curtain is used the cord 20 and mechanism thereformay be dispensed with or not as desired. In case it 1s dispensed withthe curtain is adapted to be operated by hand in the usual manner. Thecurtain is secured to the roller in such manner that when the upper sashis closed or in its normal position, the curtain hangs pendently fromthe roller a distance corresponding to the length or depth of said sash,and when the upper sash is lowered by pulling downward upon that portionof the cord 27 in rear of the curtain the curtain is wound upon theroller a corresponding distance, so that when the upper sash is entirelylowered the curtain is entirely wound upon the roller, and when the sashoccupies an intermediate position the curtain is wound a distancecorresponding to the distance between the upper rail of the said sashand the lower side of the upper portion of the window casing. Ifdesired, however, by operating the cord 20 the curtain or shade may bewound or unwound as desired.

From the above description it will be seen that I have produced windowshade appliances by which the curtain automatically winds or unwindsupon the roller as the upper sash is lowered or raised, and by whichalso the shade or curtain may be operated independently of the sash, andwhich is simple, strong, durable and inexpensive of construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a window-shade appliance, the combination with brackets secured tothe window sash, and arms detachably carried by said brackets, of agrooved roller-16, carried at the and lower ends of the window-casing,subouter end of-one of said arms, and a second stantially as set forth.grooved roller carried by said arm vertically In testimony whereofIaffix mysignaturein above the roller 16, and upon the shade rollthepresence of two witnesses.
